I read with great interest the article entitled “Partial Joint Denervation I: Wrist, Shoulder, and Elbow,” published by A. Lee Dellon in the January 2009 issue of the Journal (Plast Reconstr Surg. 2009;123:197–207). Initially Dellon holds the opinion that a neurogenic origin of pain has not yet been mentioned in differential diagnosis, and he makes the absence of illustrations of joint innervation in anatomic texts responsible. This opinion, however, does not consider the publications of Rüdinger (1859) and Gardner (1948),1) or those of Wilhelm (1958)1,2 and von Lanz and Wachsmuth (1959).3 Thus, joint innervation has been well known for a long time!
Wrist Joint. In 1966, I described the denervation of the wrist.2,4 Since that time, 95 of 139 cases have been partially denervated and 44 patients have been completely denervated. This is a ratio of about 2:1 in favor of partial denervation.4 Total denervation, which would also include the palmar articular fibers of the ulnar nerve, has never been necessary.
In the indication for pain elimination, one should always consider the results of each test blocking! The proposition to only eliminate the “critical nerve branches” should only be discussed for the time being, as there are no final results.
Shoulder Joint. The most severe pains are found in the anterior upper quadrant of the shoulder joint and over the coracoid. Mainly a direct connection of the inferior cervical ganglion by an articular branch entering between coracoid and subscapular muscle into the joint capsule is responsible. This articular branch was confirmed histologically by Gardner (1948)1 and macroscopically by me.1
Based on my own findings in 1960, a simple injection procedure was developed.1 First, the already known blocking of the suprascapular nerve is performed to eliminate the posterior articular nerves. Afterward, the articular branch of the anterior cranial thoracic nerve innervating the coracoid and finally the acromioclavicular joint is eliminated (Fig. 1). The needle is inserted over the tip of the coracoid and then infiltrates the fan-shaped soft tissue over the clavicle (Fig. 2). Then the remaining anterior articular branches are eliminated (Fig. 1). The needle is drawn back and turned over by 90 degrees and then moved to the humeroscapular joint cavity. Below the coracoid a larger depot is administered between the subscapular and coracobrachial muscles. Most articular nerves, as well as the sympathetic articular branch, run in this gliding layer. Finally, by subsequent diffusion of the anesthetic, the articular nerve endings of the deep layer, originating from the four subscapular nerves, can be blocked. An injury of the vascular nerve bundle is impossible!
Denervation of the articular branch of the acromioclavicular joint and of the sympathetic articular branch was discussed earlier in 1963.1
Tennis Elbow. I held the opinion that the success of surgery at the extensor tendons is based on an unconscious denervation as early as 1962.2 An anterior radial branch running through the brachioradial muscle has never been cut by me.
Golfer's Elbow. In addition to this communication, see my letter to the editor published in the Journal of Hand Surgery (Edinburgh, Scotland).5
